State the definition of Work. 8/4/2019 When a force acts upon an object to cause a displacement of the object, it is said that work was done upon the object. http://www.physicsclassroom.com/Class/energy/u5l1a.cfm

Identify the conditions for work to be done. 8/4/2019 In order for a force to qualify as having done work on an object, there must be a displacement and the force must cause the displacement.  http://www.physicsclassroom.com/Class/energy/u5l1a.cfm

Identify the conditions for work to be done. 8/4/2019 Read the following five statements and determine whether or not they represent examples of work. Then click on the See Answer button to view the answer. http://www.physicsclassroom.com/Class/energy/u5l1a.cfm

State the equation/relationship for Work Done. 8/4/2019 Grade 7: W = Fd Grade 8: W = Fdcosθ W = Work Done (J) F = Force (N) d = displacement (in the direction of the force) Θ = angle between the force and the displacement vector

Work Done W = Fd Grade 7 8/4/2019 W = Work Done [Joules (J) or Nm] F = force (N) d (sometimes s) = displacement in the direction of the force (m) http://physics.fisikastudycenter.com/junior-high-school-physics/82-10-common-problems- of-work-and-power-junior-physics http://www.sparknotes.com/physics/workenergypower/review/quiz.html

Work Done W=Fd cos(θ) Grade 8 8/4/2019 W = Work Done [Joules (J) or Nm] F = force (N) d (sometimes s) = displacement in the direction of the force (m) θ = the angle between the force and the displacement vectors http://www.physicsclassroom.com/class/energy/Lesson-1/Calculating-the-Amount-of- Work-Done-by-Forces

Derive base units of a Joule. 8/4/2019 One Joule is equivalent to one Newton of force causing a displacement of one meter. In other words, The Joule (J) is the unit of work. W = Fd 1 Joule = 1 Newton * 1 metre 1 J = 1 N * m
